lowing'is a specification.

The inventionrelates to an improvement in feed bags ior animals-constructed andarranged to automatically and properly-present the food to the mouth or the animal whenthe bag is in position.

.The main ob ect of the present invention resides in the production of a sim le iced:

h which the food is'au'tomatical y maiir taine atall times-in proper relation'to the mouth of the animal, the construction including a ventilating means by which fresh air is admitted to the bag while the same is in use.

The invention will be described in the following specification, reference being had to the accompanying drawings, in wlnch:-

Figure 1 is a side elevation ofajaag constructed in accordancewith my invention, Fig. 2 is a vertical central section of the same, l ig. 3 a top plan with the suspending means omitted. l lg. 1 is a vertical sectional view ota i'eedbag constructed in acordance with 1y invention, a slightly modified. arrange,- ment being illustrated, Fig. 5 is a section on, linesS-b of Fig. l, Fig. 6 is a plan of proved feed bag showing an attaching means therefor, Fig. 7 is a side elevation of the same. Referring particularly to Figs. 1, 2, and 3 of the drawings my improved feed bag'com prises a receptacle'l of flexible material, as leather or the like, open at the upper end and, rounded or of semispherical shape at the bot tom, as at 2. T he rounded shape of the bottom of the receptacle is desirable as it tends to direct all food in the receptacle toward the lowest point or center of the bottom, thereby enabling the same; to be conveniently grasped-by the lips of the animal. 7 Under constant use it is obvious that the rounded bottom 2, if unprotected would be distorted with obvious disadvantage in use, and to avoid such distortion 1 reinforce the rounded bottom 2 of the receptacle with a casing 23, preferably circularinplan and of hollow'con struction to receive'the rounded bottom, the upper edge of the side wall oi the casingbeing secured to the side wall of the receptacle by rivets 4, or other suitable fastenings. As the casing 3 is circular in plan with a flat bottom, it is obvious that with the receptacle 1, secured therein a space will be provided between the semispherical bottom of the receptacle, and the bottom side wall of the casing. This space is filled with a suitable' packing, as 5, so shaped as to brace and reinforce the bottom 2 of the receptacle 1, thus maintaining the semi-spherical form of the'latter notwithstanding continued use.

To secure a proper ventilation of the feed bag in use I provide a strap 6 of substantial Width and'oi' a leng'th somewhat in excess of half the circumference of the upper portion of The strap is termithe mouth of the bag. Hall secured at 7 to opposing points of the bag so t at the upper edge of the strap is in aliuemont-with'the upper edge of the bag. ln-

tel-mediate the points of attachment the stra .is spaced from the bag by a series of 'bloc s 8, preferably of leather or the like,

which are disposed between the proximate surfaces of the bag and strap and maintained inrelativelyspaced relation; By this 0011- struction a series of air inlets 9 are rovided which cannot be closed by the head 0 the animal in using the bag;

The bag is supported by a head strap 10 terminally connected to diametrically opposed points of the bag through the medium' of coil springs 11. The springs are so tensioned'that under normal conditions the bottom of the bag is spaced from thehighest' oint of the head strap such a distance as to o'within convenient reach of the lips ofthe animal, when the bag is applied. Therefore, under the weight of the contained food the springs 11 will be distended. As the weight Qof food is reduced'by the animal the bag will gradually rise under the influence of the springs 11, thereby automatically presenting e food within convenient reach of the animals lips at all times.

Referring particularly to Figs. 4 and 5, wherein is illustrated a slightly modified form of feed bag, the receptacle 12 is provided on its inner surface with a sealing member 13, preferably in the form of a sleeve and connected at its upper end to the upper end of the receptacle. Below the point of connection the sleeve isspaced from the wall of .the receptacle to provide for the reception within said space of the feed carrier 14. ,The

carrier is in the form of a feed bag, and is freely movable vertically within the receptacle 12, it being understood that the parts are so arranged that the relatively upper end of the carrier 14 is at all times disposed between the sealing member 13 and the wall of the receptacle. Between. the bottom of the carrier and the bottom of the receptacle is arranged a coil spring 1.5, so tensioned as to ovcrbalance the weight of thecarrier and normally maintain the same at its upward limit of movement. In the use of this form of feed bag it is obvious that the Weight of the feed within the carrier will depress the same against the tension of the coil spring, and as the food. is consumed thespring will tend to move the bottom of the carrier upward, thereby maintaining at all times a supply of food within. convenient reach of the mouth of the animal. The feed bag is provided with the form of ventilating means illustrated in- Figs. 1 to 3, and is supported through the medium of the usual or any preferred form of head strap 16. The bottom of the receptacle 12 is formed With'a series of openings 17 whereby to permit the escape of 1 any of the feed finding its way past the car rie integral with the section 21 and terminally provided wit '1 a semi-cylindrical clamping ring 23. A spring bar 24 is secured to the bar 22 adjacent its juncture with the section 21, said. bar being also-formed with a semieylind ical clamping ring 25 arranged to co operate with the ring A clip 26 slidably engages the bars 222 and 24, being so arranged that in the movement of the ring toward the free end or said bars, the clamping members 23 and 25 will be forced into proximate clamping position, the movement ol said clip in the opposite direction permitting such lree movei'nent of the clamping members as will permit their disengagement from the sup- 2 By the use of this device it is obvious that the feed bag may be conveniently supported upon any fixture in which the clamping members may co-operate, the arrangement thereof to insure the gravitation oi the food.

toward the central point.

Having thus described the invention What is claimed as new, isz I 1. A. feed bag comprising a receptacle, a strap secured to the Wall of the receptacle adjacent the upper end, and a series of blocks secured between the receptacle Wall and the strap, said blocks being respectively spaced to provide air inlets.

2. A feed bag comprising a receptacle, a

strap secured tothe wall of the receptacle adjacent the upper end, a series of blocks secured between the receptacle wall and the strap, said blocks being respectively spaced to provide air inlets, and spring means for c mnterbalan cing the weight of the feed carrier. v

3. A. feed bag comprising a receptacle, a strap secured to the wall of the receptacle adjacent the upper end, a series oi blocks secured. between the receptacle Wall and the strap, saidfblocks being respectively spaced to provide air inlets, and an adjustable clamping support removably engaging the bag.

in testimony whereof, I a'llix my signature in presence of two Witnesses.
